Episode notes
Conservative Gold Price
- Minera Alamos uses a lower base case gold price ($1800/oz) for their Copperstone PEA than many peers ($2100/oz).
- This is because it's a re-release of a prior PEA and changing the base case would require a full rewrite.
Optimization and Study Plans
- Focus on optimizing mining costs and refining engineering plans to improve project economics.
- Don't expect a PFS or feasibility study for this brownfields restart, as the existing data is sufficient.
Timeline to Production
- Copperstone aims to restart production by mid-2026, with underground development commencing late 2024.
- This timeline is conservative, adding two months to the original PEA estimate.
